Question

How many ATP are produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to $C{O}_2$and $H_{2}O$? $(18.4,18.5,18.6)$

Short answer

$32$ATP is produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to$C{O}_{2}and{H}_{2}O$.

Step-by-step solution

Given Information 

We need to find the ATP that is produced when glucose is oxidized to pyruvate, compared to when glucose is oxidized to $C{O}_{2}and{H}_{2}O$.

Simplify

The ATP produced in the oxidation of glucose to pyruvate yields only $7ATP$units. Presented below is the ATP yield of the oxidation of glucose to pyruvate.

Now, the complete oxidation of glucose to carbon dioxide$32ATP$is produced. When glucose enters glycolysis, $7ATP$ is produced. As it undergoes oxidation, the product of glycolysis is oxidized and decarboxylated to acetyl CoA yielding $5ATP$. When acetyl CoA proceeds to the citric acid cycle, acetyl CoA is further complete oxidation of glucose to carbon dioxide.
